Add more intelligence to your processes, Evgeny Vinogradov, Yandex.Money, CEE-SECR 2017

My talk will sum up some of our experience in modifications of existing processes with machine learning. I will briefly describe challenges that we face when trying to add more intelligence to static rules, what technologies was employing for that aim, and give a few clues how to solve conflicts between different result obtained on single transaction and make final decision. Talk will be interesting among architects, PM, and all that are interested in data science.
